The part is AEC-Q100 qualified and rated over the full -55 to 125 °C military-automotive temperature range, making it a fit for under-hood engine control units, body electronics, and industrial equipment that sees wide thermal swings. ## 5 Mbps and the CAN FD bus The headline 5 Mbps data rate supports CAN FD operation, where the arbitration phase runs at the standard 500 kbps or 1 Mbps and the data phase switches to the higher rate. That means the transceiver must handle the faster edge rates without excessive ringing or EMI. The TCAN1042DQ1 is specified for this, so it can be used in gateway modules or sensor clusters that need the higher payload throughput. If your design only uses Classical CAN at 500 kbps, the 5 Mbps rating still gives margin on the signal-integrity budget. ## AEC-Q100 and the temperature envelope The -55 °C low end covers cold-crank conditions and arctic storage, while the 125 °C high end handles under-hood heat soak. For industrial buyers, this same temperature grade covers motor-drive cabinets and outdoor telecom enclosures without needing a separate industrial-rated variant. That makes the TCAN1042DQ1 a drop-in candidate for board revisions that need the higher data rate or the wider temperature range.","metaTitle":"TCAN1042DQ1 CAN Transceiver, 5 Mbps, AEC-Q100, 8-SOIC","metaDescription":"Texas Instruments TCAN1042DQ1 CAN transceiver, 5 Mbps data rate, AEC-Q100 qualified, -55 to 125 °C, 4.5-5.5 V supply, 8-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Mfr":"Texas Instruments","Type":"Transceiver","Duplex":"-","Series":"Automotive, AEC-Q100","Package":"Tube","Protocol":"CANbus","Data Rate":"5Mbps","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Base Product Number":"TCAN1042","Operating Temperature":"-55°C~125°C","Supplier Device Package":"8-SOIC","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.2600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3a364d689f0172292325d2d55ebef86f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TCAN1042DQ1/alternatives.json"},"ai":{"faq":[{"question":"Is TCAN1042DQ1 AEC-Q100 qualified?","answer":"Yes, the series is listed as Automotive, AEC-Q100, which means it has passed the automotive-grade qualification tests."},{"question":"What is a direct replacement for TCAN1042DQ1?","answer":"Within the TCAN1042 family, the base product number TCAN1042 covers multiple variants.
